Story:
Black Dog traveled to the Germany of the Third Reich in the 40s to the residence of an Austrian Painter,
but the "Austrian Painter" himself opens the doors
(I say this because I don't want to say his name without censorship for Politically Incorrect) Seeing that,
Black Dog manages to kill the "Austrian Painter" easily by shooting a bullet from his finger guns,
when he believes that the world has returned to normal,
Black Dog sees that everything was different and when he turns from behind he is scared to the Black Dog,
it was again the "Austrian Painter" but giant and he gets enraged and takes the time machine that the Black Dog used,
"Austrian Painter" tries to catch Black Dog but the Black Dog managed to dodge him by jumping on the other side,
a Cannon Gun falls next to it and Black Dog upon seeing it seems like an idea,
Black Dog uses the Cannon Gun to shoot the Giant "Austrian Painter" but a single shot did not affect anything,
Black Dog screams in horror and runs away.
He hides in the wooden latrine for a few seconds and then he comes out with a missile launcher
and it was a Waluigi missile launcher loaded and Waluigi's missile shoots it in the direction of
the "Austrian Painter's" face and the screen crashes (Breaking the Fourth Wall) and then it explodes
and finally the " Austrian Painter" exploded, leaving only the Black Dog as victorious and begins to dance
with A-ha's "Take on Me" song in the background
but Black Dog's Time Machine falls on top of him and he teleports and disappears alone to travel in another era.
